Thanks for the help guys. Coating in and outside it is

But does it apply to the dump pipe as well and is it worth doing?
Not trying to be cheap on the dump pipe. I just dont want to do the dump pipe as i need steve from MMS to make one to suit my twinscroll/catback and i use my car as a daily. But if it makes a difference, then a few more days wont hurt i guess..That and i want to get the gear fitted and tune asap. end csb
